This invention has to do with making articles, particularly loose-leafbinders, provided With pockets for the reception of cards or the like toindicate the contents or whatnot of the articles.

Loose-leaf binders have not generally been provided with such pocketsbecause they were too unsatisfactory. The metal pockets soon becomedistorted, making it diflicult to insert or remove a card and also theyare likely to catch on and damage themselves or other articles with:which they come in contact. The fabric type which is usually stitchedto the outside of the binder covering soon wears through the stitching,allowing the pocket to separate from the coverlng. Usually this typealso has a piece of transparent material stitched to the edges of thewindow and this material soon becomes so scratched that it is difficultto see through it, thus making the pocket useless.

Our invention resides in a loose-leaf binder provided with a pocketwhich eliminates all of the above disadvantages by being mounted whollybeneath the binder covering so that there no projections to interferewith its use or be likely to wear out. 'I'he card is well protectedagainst wear, and if a transparent cover is used for the window it canbe replaced when it becomes scratched. Our pocket can be included duringthe manufacture of binders .with little or no ad-` ditional cost. Inaddition to its usefulness for which it Was designed, the pocket givesthe binder a neat and nished appearance.

Other advantages will be pointed out in the following detailedspecification with reference to the attached drawing in which:

Figure 1 is a perspective View of a fragment of a binder which embodiesour invention.

Figure 2 is a view showing a blank employed in the production of ourpocket, creased to facilitate folding, but not yet folded.

Figure 3 is a view of the blank after it has been folded.

Figure 4 is a section along line 4- of Figure l.

Figure 5 is a section along line 5 5 of Figure 1.

In the drawing, the numeral I indicates in a general way a loose-leafbinder having leaf members 2 and 3 and a back member 4 which spaces theleaf members apart. There is usually provided a supporting mechanism,not shoIwn, carried by the back member 4 between leaves 2 and 3 andwhich is adapted to support loose-leaf material. These leaf and backmembers are usually made of relatively stiff binder-board so that theywill retain their shape. Extending around the outside and completelycovering the ures 4 and 5,

leaf and back members and attached thereto as by gluing is a covering offlexible material 5. It is customary in binders also to have a exiblecovering 6 for the inside of the leaf and back members. As shown at 'Iand 8, covering 5 and forms a hinge between each of the leaf members andthe back. This is the usual construction of loose-leaf binders and formsno part of our invention except in its relation to our pocket which willnow be described.

Numeral 9 represents a piece of relatively tough flexible materialcapable of being creased and folded into shape Without cracking orbreaking. We have found that a brous material, capable of absorbing someof the glue with which the covering is attached is best suited for thispurpose. However, other materials such as metal could be used. Thematerial is blanked out to the shape shown in Figure 2 with the cornerI0 removed. During the blanking operation, the material is slightlycreased along the lines I2, I3, I4 to outline front and back parts I5and I6 and flanges II and Il and facilitate folding of the blank intothe pocket form shown in Figure 3. The blank is then folded along thelines I2, I3 and I4 with the flanges II and I'I folded over and glued orotherwise attached to the part I6 as shown at I8 and I9. This gives acomplete pocket 20 which is open at one end as shown at 2|. The methodof making this pocket from a single piece of material is merely thepreferred method and it is obvious that it could be assembled fromseparate pieces or otherwise.

The pocket is attached, as shown at 22 in Figto the face of the backmember 4 prior to the application of the covering material 5. We preferto attach the pocket to the back member so that it will not be displacedwhen the covering is applied. We nd it more satisfactory to attach thepocket so that the flanges II and I'I face the backing member.

After the pocket is attached, the covering 5 is applied by gluing it tothe leaves Zand 3, back 4, and also the outermost layer 23 of thepocket. Then an opening 24 is cut through the covering material 5 alongthe edge 25 of the open end of the pocket. Through this opening accessmay be had to the pocket for the insertion or removal of a card or thelike 26 and the transparent cover 21.

The window 28 is cut through the covering 5 and through the outermostlayer 23 of the pocket. Through this window the card or the like 26 maybe seen. We nd it desirable to cut 'ing member and 2 the opening 24 andwindow 28 in a single operation by means of a. die for that purpose.

The term binder as used throughout the idescription is only for thepurpose of illustration as our pocket could obviously be used on anyarticle for which it is adapted.

We claim:

The method of making an article which includes a backing member, acovering therefor, a ilattish windowed pocket between the backing memberand the covering and an opening in the covering which leads into thepocket, which includes: completely forming a member with substantiallyparallel attish walls spaced `apart to define a flattish pocket andanopening which l leads into one end of the pocket, applying the completedpocket deiining member to the backparallel fiattish walls to one side ofthe backing member, applying covering material to the side of thebacking member to which the pocket dening member is bonded and to thepocket dening member and bonding the covering material to the backingmember and the pocket dening member and, thereafter, cutting a windowthrough the covering material opposite the pocket defining member andthrough the attish wall of the pocket dening member to which thecovering material is bonded and cutting through the covering material anopening which leads into the opening which leads t into the end of thepocket in the pocket dening 5 member.
